PURPOSE:To locate correctly a printing part by correcting the inclination of a printing part with only detecting the mark center position and by using the sliding accompanying thereby in case of locating a stock on a press machine by visual means. CONSTITUTION:A press blanking print part and the nearby piece of stock 1 where numerous marks for locating are printed are pinched with a freely turnable clamping means within on the plane face X-Y and said clamping means is moved in the directions of axes X, Y. The center position of said mark is then detected by the camera 11 being arranged at the prescribed position for a press machine 10. The inclination opposing to the axis X direction of said printing part is calculated from the center position of more than two marks thus detected and said clamping means is turned in the direction to offset the inclination thereof by this inclination. The gap in the axes X, Y directions of said center position following said rotation is calculated from the distance between the turning center of the means and this rotated angle and said mark center position, and said printing part is located to the machine 10 based on this gap and said marks center position. |
